openEuler
In this guide, you will deploy MyEMS on openEuler server.
Prerequisites
This guide describes how to install MyEMS on openEuler 23.03. Hardware requirements depend on chosen database and amount of devices connected to the system. To run MyEMS and MySQL on a single machine you will need at least 4GB of RAM.
Clone source code:
cd ~
git clone https://github.com/myems/myems
Step 1 Database
See Database
Step 2 myems-api
- Install myems-api service:
sudo cp -r ~/myems/myems-api /myems-api
cd /myems-api
sudo pip install -r requirements.txt
Create .env file based on example.env and edit the .env file if needed:
sudo cp /myems-api/example.env /myems-api/.env
sudo nano /myems-api/.env
Add port to firewall:
sudo firewall-cmd --zone=public --add-port=8000/tcp --permanent
sudo firewall-cmd --reload
Setup systemd configure files:
sudo cp /myems-api/myems-api.service /lib/systemd/system/
sudo cp /myems-api/myems-api.socket /lib/systemd/system/
sudo cp /myems-api/myems-api.conf /usr/lib/tmpfiles.d/
Next enable the services so that they autostart at boot:
sudo systemctl enable myems-api.socket
sudo systemctl enable myems-api.service
Start the services :
sudo systemctl start myems-api.socket
sudo systemctl start myems-api.service
Step 3 myems-admin
- Install NGINX Server
refer to http://nginx.org/en/linux_packages.html#RHEL
Enable the nginx service:
sudo systemctl enable nginx.service
- Configure NGINX
sudo nano /etc/nginx/nginx.conf
In the 'http' section, add some directives:
http {
client_header_timeout 600;
client_max_body_size 512M;
gzip on;
gzip_min_length 512;
gzip_proxied any;
gzip_types *;
gzip_vary on;
proxy_buffering off;
...
}
Add a new file under /etc/nginx/conf.d/:
sudo nano /etc/nginx/conf.d/myems-admin.conf
Write with directives as below, and replace the default myems-api url http://127.0.0.1:8000/ with actual url if the myems-api servcie hosted on different server
server {
listen 8001;
server_name myems-admin;
location / {
root /var/www/myems-admin;
index index.html index.htm;
}
## To avoid CORS issue, use Nginx to proxy myems-api to path /api
## Add another location /api in 'server'
## Replace the default myems-api url http://127.0.0.1:8000/ with actual url if the myems-api servcie hosted on different server
location /api {
proxy_pass http://127.0.0.1:8000/;
proxy_connect_timeout 75;
proxy_read_timeout 600;
send_timeout 600;
}
}
- Install myems-admin: If the server can not connect to the internet, please compress the myems/myems-admin folder and upload it to the server and extract it to ~/myems/myems-admin
sudo mkdir /var/www
sudo cp -r ~/myems/myems-admin /var/www/myems-admin
sudo chmod 0755 -R /var/www/myems-admin
Check the config file and change it if necessary:
sudo nano /var/www/myems-admin/app/api.js
The 'upload' folder is for user uploaded files. DO NOT delete/move/overwrite the 'upload' folder when you upgraded myems-admin.
/var/www/myems-admin/upload
Unlock the port and add the port to firewall:
sudo firewall-cmd --zone=public --add-port=8001/tcp --permanent
sudo firewall-cmd --reload
Restart the nginx service:
sudo systemctl restart nginx.service
If you encounter '403 Forbidden' nginx error, you may fix it by changing SELinx mode with command 'sudo setenforce 0'
Step 4 myems-modbus-tcp
In this step, you will install myems-modbus-tcp service.
sudo cp -r ~/myems/myems-modbus-tcp /myems-modbus-tcp
cd /myems-modbus-tcp
sudo pip install -r requirements.txt
Copy exmaple.env file to .env and modify the .env file:
sudo cp /myems-modbus-tcp/example.env /myems-modbus-tcp/.env
sudo nano /myems-modbus-tcp/.env
Setup systemd service:
sudo cp myems-modbus-tcp.service /lib/systemd/system/
Enable the service:
sudo systemctl enable myems-modbus-tcp.service
Start the service:
sudo systemctl start myems-modbus-tcp.service
Monitor the service:
sudo systemctl status myems-modbus-tcp.service
View the log:
cat /myems-modbus-tcp.log
Step 5 myems-cleaning
In this step, you will install myems-cleaning service.
sudo cp -r ~/myems/myems-cleaning /myems-cleaning
cd /myems-cleaning
sudo pip install -r requirements.txt
Copy exmaple.env file to .env and modify the .env file:
sudo cp /myems-cleaning/example.env /myems-cleaning/.env
sudo nano /myems-cleaning/.env
Setup systemd service:
sudo cp /myems-cleaning/myems-cleaning.service /lib/systemd/system/
Enable the service:
sudo systemctl enable myems-cleaning.service
Start the service:
sudo systemctl start myems-cleaning.service
Monitor the service:
sudo systemctl status myems-cleaning.service
View the log:
cat /myems-cleaning.log
Step 6 myems-normalization
In this step, you will install myems-normalization service.
sudo cp -r ~/myems/myems-normalization /myems-normalization
cd /myems-normalization
sudo pip install -r requirements.txt
Copy exmaple.env file to .env and modify the .env file:
sudo cp /myems-normalization/example.env /myems-normalization/.env
sudo nano /myems-normalization/.env
Setup systemd service:
sudo cp /myems-normalization/myems-normalization.service /lib/systemd/system/
Enable the service:
sudo systemctl enable myems-normalization.service
Start the service:
sudo systemctl start myems-normalization.service
Monitor the service:
sudo systemctl status myems-normalization.service
View the log:
cat /myems-normalization.log
Step 7 myems-aggregation
In this step, you will install myems-aggregation service.
sudo cp -r ~/myems/myems-aggregation /myems-aggregation
cd /myems-aggregation
sudo pip install -r requirements.txt
Copy exmaple.env file to .env and modify the .env file:
sudo cp /myems-aggregation/example.env /myems-aggregation/.env
nano /myems-aggregation/.env
Setup systemd service:
sudo cp /myems-aggregation/myems-aggregation.service /lib/systemd/system/
Enable the service:
sudo systemctl enable myems-aggregation.service
Start the service:
sudo systemctl start myems-aggregation.service
Monitor the service:
sudo systemctl status myems-aggregation.service
View the log:
cat /myems-aggregation.log
Step 8 myems-web
In this step, you will install myems-web UI service.
- Install NGINX Server
refer to http://nginx.org/en/linux_packages.html#RHEL
- Configure NGINX
sudo nano /etc/nginx/nginx.conf
Remove default files
sudo rm /etc/nginx/sites-enabled/default
sudo rm /etc/nginx/conf.d/default.conf
Add a new file under /etc/nginx/conf.d/
sudo nano /etc/nginx/conf.d/myems-web.conf
Add a new 'server' section with directives as below:
server {
listen 80;
server_name myems-web;
location / {
root /var/www/myems-web;
index index.html index.htm;
# add try_files directive to avoid 404 error while refreshing pages
try_files $uri /index.html;
}
## To avoid CORS issue, use Nginx to proxy myems-api to path /api
## Add another location /api in 'server'
## replace the default myems-api url http://127.0.0.1:8000/ with actual url if the myems-api servcie hosted on different server
location /api {
proxy_pass http://127.0.0.1:8000/;
proxy_connect_timeout 75;
proxy_read_timeout 600;
send_timeout 600;
}
}
- Install MyEMS Web UI:
Setup NodeJS:
sudo dnf install nodejs
Modify the config.js file:
Get mapboxToken at https://mapbox.com and then set showOnlineMap to true. If you wnat to turn off online map feature, set showOnlineMap to false
cd ~/myems/myems-web
sudo nano src/config.js
Build and Compress
sudo npm i --unsafe-perm=true --allow-root --legacy-peer-deps
sudo npm run build
Install Upload the files to you web server. Note that the following path should be same as that was configured in nginx.conf.
sudo mv build /var/www/myems-web
Unlock the port and add the port to firewall:
sudo firewall-cmd --zone=public --add-port=80/tcp --permanent
sudo firewall-cmd --reload
Restart the nginx service:
sudo systemctl restart nginx.service
If you encounter '500 Internal Server Error' nginx error, you may fix it by changing SELinx mode with command 'sudo setenforce 0'
